Secured t'o the memberY 20 as for example byv the capscrews 21--21, is the gasier 22, having novel features which will be described. The housing whichA comprises the manifold ,2o also provides a pas"' sageway tol be referred to hereinafter, communi;` eating with the outlet of said 'gasien which pas; sageway conducts gas from said gasfier intocfonf' ytact with the walls of the passageway for exhaust' gases, whereby said Walls will effect a changeih' the direction of the gas delivered by said gasiei" and also transfer heat from the exhaust' gases to the gas delivered by said gasier. Said gasier 22 has means for admittinga regulatable supply of oil and a regulatable supply of air'. The How' of oil and air is preferably responsive tothe forcel which causes the flow of air into the cylinders of the engine, whether said flow of air into the cylinders of the engine be due to the suction of the engine or due to a means for setting up a superatmospheric pressure, as for example, a supercharger. The gasifier 22 operates generally under the principles described and claimed in applicants copending applications Serial No. 492,237 and Serialv No. 752,049. rIhe gasier disclosed in the present application, however, has certain features not disclosed in the prior applications referred to, which features contribute toward greater efficiency and compactness.

The gasier 22 comprises a receptacle, which for purposes of description may be said to include a combustion chamber 23 and a gasifying chamber 24. From an inspection of Figure 3, it will be noted that communication between the combustion chamber 23 and gasifying chamber 24 is provided through the neck 25, which neck is unsymrnetrical relative to the chambers 23 and 24. Communicating with the chamber 23 is the nozzle 26 for delivering a mixture of oil and air into said chamber 23. Said` nozzle has novel features of construction, which will be referred to hereinafter, and sprays a mixture of atomized fuel into said chamber 23. A spark plug 27 is provided for igniting the mixture of fuel and air within said chamber 23.

It will be noted that the walls of the chamber 23 converge toward 'the neck 25. The wall 28 of the chamber 24 may be substantially fiat on its inner surface, but the inner surface of the opposed wall 29 of said chamber 24 is of rounded or g globular form, whereby to provide a pocket which will promote the setting up of a swirl within said chamber 24. As noted above, the neck is not symmetrical with the chambers 23 and 24 but is inclined relative to the axis of the nozzle 26, the

side 30 of the neck`25 adjacent to the wall 29 being closer to said nozzle than is the opposite side of said neck 25. By reason of the construction illustrated, swirls of the material within the chamber 24 will have a tendency to project particles of material upwardly through the neck 25 into the chamber 23 for the purpose of submittingV said particles to treatment within the combustion chamber 23.

The means for admitting a regulatable supl ply of air and oil to the gasier 22 and the means for insuring a quick starting of the gasifying functions will now be described. Disposed at the extremity of the gasiner 22, spaced from the manifold 20, is the housing 31, which provides the oil inlet 32 and the valve seats 33--33, which disks 46 and 41, of which the disk 40 is adjustably fixed relative to the housing 31. The disk 41 is Ynon-rotatably but slidably secured to the needle valve 34. Said disks and 41 have cooperating apertures 42, which may be of any preferred contour, which apertures are adapted to be moved into and out of registry with one another for controlling the flow of air therethrough. The needle valve l34 is urged to its seat by means of the spring 44. The presentinvention contemplates means whereby the needle valve 34 is opened as the disk 41 is turned to increase the effective area of the apertures 42-42 in the cooperating disks 40 and 41. According to the illustrated embodiment of the present invention, the disk 41 is provided with the lever 45, which may be controlled from the dashboard of an automobile or the like, as, for example, like the choke of an automobile. Said disk 4l is provided with a plurality of cam-shaped wedging members 46--46 adapted to cooperate with a pin 47 connected to the needle valve 34. As the lever is turned for the purpose of moving the disk 41 relative to the disk 40, the members 46-46 will wedge the pin 47 outwardly to open the corresponding needle valve 34. It will be understood that the disks 40 and 41 may be held in engagement with one another by any preferred means (not illustrated). The disk 40 is held in adjusted position by means of capscrews 48, which engage the edge portion of the disk 40 to hold same tightly upon a corresponding seat in the housing 31. The needle valve 35 and the air inlet valve 39 may be 'the samein essential particulars as theneedle valve 34 and air inlet valve 38. Accordingly, no detailed description of the needle Valve`35 and the air inlet valve 39 are necessary. The lever 45 connected with the disk 41 of the air inlet valve 39 is connected to be operated by means cooperating with thevair inlet means of the internal combustion engine in a manner which will be referred to further hereinafter.

The oil inlet 36 communicates with a vchamber 49, which is disposed within the passageway 59, which has communication with the air, inlet valve 38. Said chamber 49 has apertures 51,-51

in its side wall communicating with the passageway 50. The lower extremity ofthe chamber 49 is provided with the wall 52, which wall is disposed in angular relationship with the oil inlet 36. The lower extremity of the oil inlet 36 is flared, as indicated by the numeral 57 (see Figures 8 and 9), said flared extremity being notched to provide distributing points 58458. The end wall 56 of the chamber 49 lis provided with an aperture 59 disposed adjacent to the extremity of the oil inlet 36, whereby oil deliveredthrough the oil inlet 36 may pass through the aperture 59. TheV passageway has a portion 56A of generally cylindrical contour, having its axis substantially coincident with the axis of the oil tube 36, and having vanother portion 50B of generally cylindrical contour, having its axis inclined from the axis of the tube 36 toward Athe axis of the tube 37. A recess 50C communicates with the portions 56A and 50B of the passageway 50,which recess 50C contains a tube 66 which is bent intermediate of its length to have axes parallel with the axes of the portions 50A and 50B of the passageway 50. The upper extremity of said tube 60 communicates with the air valve 33. The said 1' tube 60 has apertures 61-61 adjacent to the wall 56 of the chamber 49, but is imperforate for a considerable portion of its length. The ring points of the spark plug 27 are disposed substantially at a level indicated by the line62. Below the imperforate portion of the tube 69, said tube is provided with a plurality of apertures 63-63. The lower extremity of the tube 60 is preferably closed. Said apertures 6l and 63 need be located only on that side of tube 60 adjacent to the passageway 50.

The nozzle 26 will now be described. Said nozzle includes the cylindrical member 64 having the bottom wall 65, which bottom wall is diametrically slotted, as indicated by the numeral 66 in Figure 7. Adjustablyfcarried' within the cylindrical member 64 are a pair of fingers 67 and 68 (Figure 4) ,which fingers are secured to a common member 69, the position of which may be adjusted bymeans of the screw-threaded shaft 70. By turning said shaft 70, the member walls are preferablyY provided with ame plates 73--78, which may be composed of metal which will stand very high temperatures without `deterioration. Metal suitable for theipurpose may be chosen from alloys of, nickel `and chromium, certain of such alloysl being known Ain the trade as Nichrome and Q-alloy. The flame plates should be of relatively thin gauge material, whereby they will quickly reach at least a red heat. Said flame plates may have fingers 74-74 projecting therefrom, which aid materially in combustion. Said flame plates 73-73 have very valuable functions in the operation of the prese ent invention due to their catalytic action upon the rmixture of oil and air beinggasied. The cylindrical member 64 is provided with the apere tures 75 (see Figures 3 and 4), which permit the passage of air from the airinlet valve 39 through the cylindrical memberr 64 to the combustion Y chamber 23. The lower extremities of the flame is provided bythe casing 79. Said casing 79 hasl communication to the atmosphere inthe construction shown in Figures 1 andB through the valve 80, which comprises a hollow piston provided with a closed end 80A and a plurality of apertures ill-48,1 in its side wall. Said piston 80 is disposed withinra wallof the casing 79 and'is adapted to admit air to said casing when vsaid piston is raised a sufiicient distance to provide access from the interior of said piston to the Vinterior, of said casing 79 through the apertures 8l. `Said .piston 80 i's'connectedy to the lever 45 connected to the rotatable disk 41 of the air inlet valve 39. Weights 82,-82 may be provided for adjusting the force tending to `close the piston valve 80.*- The numeral 83 indicates a bell crank having a connection through the rod 84 to any convenient operating means,l such for example,

- as the accelerator or fuel feedingf button of an automobile or the like. Said bell crank lever 83 isl provided with anend portion 85 adapted to press downwardly upon a pin 86 secured to the piston rod 87 secured to the piston 80.

t will be noted that the gas produced by the gasifier 22, in passing from the gasier, Vis directed against the wall 88, which` comprises the top wall defining the passageway for exhaust gases passing through the exhaust manifold 20.` Said gas also passes in contact withl the side Walla 88A of said passageway. In the operation of the gas engine having the exhaust manifold 20', saidV walls 88 and 88A will, of course, be at high tem-v perature. By reason of the fact that the gas passing from the gasier 22 passes in proximity to the walls of the exhaust manifold 20, said gas will be maintained at high temperature up to the instant it passes into the cylinders of the engine. Moreover, inasmuch as the gas from the gasier 22 strikesl the wall 88A in a direction perpendicular to said wall, the tendency to deflect gases back into proximity with the nozzle 26 isstill further increased and ystratification of said gas is minimized. vAnother advantage of this construction vis that the danger of flames from the gasier reaching the region of commingling of the gas with the air from passageway 7-8 is reduced.

By reference to Figures 6 it will be noted that a baille 89 isy provided for separating the gas from the passageway 76 from the air entering through the passageway 78, until said gas and air have entered a material distance into the intake manifold 77. Said baille 89 serves a double purpose. First,v it provides a safety feature with the. advantage thaty if flames from the gasifying chamber 24 should shoot down through Athe passage-v way 76, such flames will not reach the region at which the gas from the gasifier 22 mingles with the air from the passageway 78; and second, by 105 reasonk of the fact that the air from the passageway 78 isdirected tothe intake manifold 77in substantially parallel relationship with the stream of gas from the gasier, the incoming air will have an aspirating effect upon the gas, i-mproving the operation of the gasier.

Referring now to Figure 12, the numeral 90y indicates a pipe, which may lead to a blower such as used in a supercharger for an internal com-y bustion engine. Referring to Figure 13, the numerals 91w91 indicate pipes leading to said blower. Said pipes 90 and91 may be supplied with air at superatmospheric pressure from thek same blowing means. The numeral 92 indicates'- a valve connected to lever 45 of the oil inlet valve 120 35, whereby said oil inlet valve willv vary its opening in-response to the flow of air to the passageway'7 8 and to the nozzle 26.

1 The mode of operation of the above described embodiment of the present invention is substantially as follows. Relatively heavy oil may be admitted through the loil inlet 32. Air either fromv the atmosphere or from the blower of a supercharger is admitted through the valves 88 and 39. Referring to the operation of the invention in combination with an internal combustion engine, it may be stated that the crank shaft of thev internal combustion engine will be turned in the usual manner for starting purposes. Referring particularly to an engine which operates-upon the suction principle, the turning over of the crank. shaft of the engine will induce a subatmospheric pressure in the intake manifold 77, which intake manifold communicates with the passageway 76. and with the passageway v'.78 in the casing 79. In starting, the lever 45 will be turned-by the operator. in a direction to move the apertures 42-42 in the disk 4l into communication with the apertures 42 in the disk 4o. This communication allows air to pass into the passageway 50. Turning. movement of the disk 4l of the valve 88 pro duces a camming actionupon the corresponding, pin 47 by reason of the engagement of the wedgev ingv member46-46 with ,said pin 47. Rotative movement -of the disk4l to admit air tothe pas-15g through the aperture 59.

:j nition by said spark plug.

sageway 50 therefore also results in axial opening movement of the needle valve 34, allowing oil to pass from the oil inlet 32 into the oil inlet pipe 36. Said oil collects upon the distributing points 58-58 at the lower extremity of the inlet pipey 36, and presents a relatively large surface area for contact with the surrounding air. Primary air, entering through the chamber 49 atomizes the oil which has collected at the outlet of pipe 36 and said atomized oil will be projected through the aperture 59. The atomized mixture of oil and air passing through the aperture 59 is ignited by the spark plug 27, which, as noted above is located at or about the level of the line 62 in Figure 3, additional or secondary air for combustion being provided by the air delivered through the apertures 51-51 in the chamber 49. In addition, air is supplied through the apertures 6l -'6l in the tube 60, though in practice it may be preferred to omit said holes 61-61.

The holes 63-63 in the tube 60 are located beyond the region at which the spark plug 27 ignites the atomized oil, whereby the jets of air from said apertures 63 will not interfere with ig- Said apertures 63 direct air transversely to the flow of the atomized fuel from the aperture 59 and cause a decided agitation in the stream of atomized fuel, causing said stream to burn with a blue fiame, indicating complete combustion. By reason of the thorough agitation provided, the oil delivered through the inlet tube 36 is totally consumed, whereby the gasifier and adjoining parts are quickly heated. The reduction of pressure within the "i: intake manifold 77 due to the suction of the gf piston, allowing air to enter the passageway 78.

Lifting of the piston 80 will result in movement of tie lever Ll5 of the air inlet valve 39 to permit the entrance of air through said valve 39. Movement of said lever will also have the result f* .jof producing a camming action between the members 46-46 and the pin 47 of the needle valve 35, opening said needle valve 35 and permitting oil to pass from the inlet 32 to the oil inlet 37. Oil will pass through the oil inlet 37, which oil 'j will be atomized by the air Which has entered through the valve 39. Fingers 67 and 66 will cause the deflection of the atomized oil, and said atomized oil will be ignited by the fiame produced by the burning of the oil and air delivered It will be understood, of course, that by regulating the rod '70, the position of the ngers 67 and 68 relative to the cylindrical member 64 may be adjusted, whereby said fingers may be set to correspond to the grade of oil being used. Said fingers divert the atomized fuel into proximity with the flame plates 73-73 and also cause the stream to flow at a lower velocity, whereby the stream of atomized fuel travels at a rate below the rate of flame propa- 1j gation. It will be clear that by diverting a part of the stream in a properly constructed chamber7 the rate of flow of the diverted portion can be brought down to and below the rate of flame propagation. Assuming that the diverted portion of the stream of atomized fuel is properly .to a gaseous state.

of flame produced and mixed with the main stream, the more nearly will the main stream of the fuel be converted into a fixed gas. Since the main stream is projected through the flame and is heated by direct contact with the flame, a very efficient heating isobtained. As noted above, a portion of the atomized oilv delivered by the oil inlet 37 is projected against the ame plates 73-73. Said flame plates 73-73 have serrated edges and projections extending into the projected portion of the main stream of atomized fuel, resulting in a thorough mixture of said projected portion of the projected fuel and retarding the iioW of that part of the atomized fuel coming in Contact with said flame plates. Each projection of the fiame plates 73-73 reduces the velocity of flow and causes a change in direction which efectually reduces the rate of flow below the rate of flame propagation. Moreover, the flame plates 73--73, after they Vbecome heated to a red heat or above, have a catalyticA action upon the atomized fuel, still further improving combustion. Air for providing complete combustion of the superficial particles of the fuel stream is provided through the apertures 75-75 in the cylindrical' member 64, which air burns in the gaseous atmosphere. The gaseous fuel, the superficial particles of which are burning with a blue` flame within the chamber 23, is projected through the neck 25 into the gasifying chamber 24. As noted above and as shown in-Figure 4, the lower extremities of the fiame plates 73 are bent inwardly from the walls of the chamber 24 forming a restriction. Moreover, the outlet of the chamber 24 is restricted relative to the globular wall 29 so that the force of the fuel from nozzie 26 tends to cause gas to be defiected back into proximity with said nozzle 26 for more complete combustion with the air emitted from the holes 75. This deflecting action is aided by the Wall 88 of the exhaust manifold 22. The i'iat wall 28, the rounded or globular wall 29 and the angularly disposed necl 25permit the efhcient defiecting of the gas in the manner just referred to. Very thorough treatment of the Vgaseous fuel is therefore assured, the superficial particles of the fuel burning with a blue flame and traveling in a swirling path, which prevents the deposition of carbon upon the walls of the gasier. .The gasified fuel from the gasifler 22 and air from the piston valve are intermingled in the inlet manifold 77 andare delivered to the cylinders of the engine in heated condition, rendering the starting of the engine comparatively easy. The passage of exhaust gases through the exhaust manifold 20 results in the heating of the walls 88 and88A, which walls are in position to communicate 'heat to the gasified fuel passingl from the gasifier 22, raising the temperature of said gas to a'still higher point. Inasmuch as the upper surface 88 of the passageway for exhaust gases is so positioned that the gas impinges thereon, said surface helps in causing a more homogeneousmixture of the gas. Inasmuch as this mixture occurs ink avery highly heated state, a gas is delivered to the inlet manifold which is quite homogeneous, avoiding difficulties which might occur through stratification.

As noted above, the piston valve 80 is weighted as for example, by means of the Weights 82-82. Said weights 82-82 may be so chosen that a balance is preserved between the air required for combustion Within the gasier and the air required to mix with the gasif'led fuel delivered from said gasifier. Y

It will be noted that if the engine should fail, for any reason, whereby a subatmospheric pressure would not be induced within the passage- .way "78, the piston valve 80, being weighted, would fall, carrying with it the lever 45, resulting in turning movement of the corresponding disk 4l of the valve 39, which would move the wedging members 46 out of camming relationship with the .pin 47, and allowing the needle valve 35 to close. By reason of V'this construction, therefore, there will be no iow of oil into the gasiiier when the engine is inoperative. From an inspection of Figure 1 it will be noted that the inlet manifold '77 is a branched manifold having the two passageways '77A and 77B, each of which passageways may `feed a multiplicity of cylinders. The air passing from the passageway '78 passes through the manifold to the two passageways 77A and 77B, the passage of said air having an injector action relative to the gas passing from the gasier 22 through the passageway 76. Said injector action at least partially overcomes the friction to which iiuid is subjected in passing through the gasiiier 22, which friction is greater than the friction of the air passing through the passageway 78.

As noted above, the bell crank lever 83 may be connected to a fuel feeding button of a selfpropelled vehicle.` The subatmospheric pressure 'within the passageway 78 will tend to cause an opening movement of the piston valve 80, which opening movement will be resisted by the end portion '85 ofthe bell crank lever 88. Y The amount of this resistance will be controlled bythe rod 84 which may be biased to a position in which valve'80 is held closed, but which may be moved from biased position by pressure on a gas feeding button or the like.

By reason of the present invention, a gasifier is provided which is relatively compact, which may be readily started, and which cooperates in a most eiiicient manner with an internal combustion engine, whereby upon turning over the engine, as in the ordinary starting process, the ignition having been turned on and the ordinary choke having been operated, the gasiler will be started andv in a very short period of time will deliver a heated gas to the engine in combination Iwith the necessary air to form a combustible mixture for enginerunning purposes. A predetermined ratio is maintained between the gas and -air ventering the inlet manifold and moreover the "means 4'for setting up a superatmospheric presysure. I
